Struct COptions 

pub struct COptions { /* private fields */ }

A pinned, owned array of cpdb_option_t with backing CString storage.

The strings cannot be reallocated after construction, so raw pointers embedded in the cpdb_option_t entries stay valid for the lifetime of the COptions. Allocation in to_c_options therefore cannot invalidate any pointer captured here.

Implementations

impl COptions

pub fn as_mut_ptr(&mut self) -> *mut cpdb_option_t

Returns a raw mutable pointer to the underlying option array, suitable for passing to cpdb-libs functions that expect a cpdb_option_t * plus a length.

pub fn len(&self) -> usize

Number of options held.

pub fn is_empty(&self) -> bool

true when no options are stored.
